工事並びに内実及び中空の壁工事に適合している。The expansion plug of the invention differs from that of the prior art in that the axially extending corners of the expansion tongue ensure positive guidance in the plug receiving hole and prevent rotation of the metal expansion plug. That is the point of blocking. The corners of the expansion tongue are pushed into the wall of the plug receiving hole with a high specific pressure during the expansion operation, which ensures a secure retention. Metal expansion plugs are suitable for concrete work and solid and hollow wall work.

圧が達成される。A quadrilateral expansion tongue can be achieved by forming four expanding tongues with a square cross-section inside the square outer cross-section by means of two slits parallel to the outer surface. Is. In this case, high surface pressure is achieved at the corners of the extended tongue.

ることによって達成される。A reliable guiding action when inserting the metal expansion plug into the plug receiving hole is achieved by the circumscribed circle defined by the polygonal outer contour having a diameter larger than the diameter of the expansion plug receiving hole. To be done.
【0009】裂開に対する安全性は、拡張舌部の外側部
上に軸線方向に対し横方向に延びるノッチを配置するこ
とによって、これを高めることができる。The safety against dehiscence can be increased by arranging a notch extending transversely to the axial direction on the outer side of the expanding tongue.

線の長さは、拡張受容孔5の直径よりも大きい。The illustrated metal expansion plug 1 has a square cross section. However, it is also possible to have another polygonal cross section, for example a hexagonal cross section. Metal plug 1 at the tip
Is divided into four square extension tongues 3 by slits 2 parallel to the sides. The inner surface 4 extends conically and has threads. The diameter of the circumscribing circle or the length of the diagonal line of the outer cross section is larger than the diameter of the expansion receiving hole 5.
【0012】金属拡張栓1の角部領域には、軸線方向に
対し横方向に配向されたノッチ6が形成されている。In the corner area of the metal expansion plug 1, a notch 6 is formed which is oriented laterally with respect to the axial direction.
